Polaris’ best in-ground automatic pool cleaner for vinyl or fiberglass surfaces, the Polaris 165 can be installed in minutes, plugging into a pool wall return jet and using the power of the existing filter pump. The 165 uses a patented jet sweep assembly that blows water against the pool wall to loosen debris in hard-to-reach places even if the pool has an uneven bottom. The debris is then blown by the jets into an easy-to-remove filter bag.
